title: Premature sebaceous hyperplasia in an adolescent boy.
abstract: Sebaceous hyperplasia is a common, benign condition of the sebaceous glands in adults of middle age or older, occurring primarily on the face and neck. In adolescent or young adult patients, it is a rare entity called premature sebaceous hyperplasia (PSH). Previous reports indicate that the onset of PSH occurs during or shortly after puberty, with an average age-at-onset of 19 years. Here we present an extremely rare prepubescent case of PSH that developed on the right side of a boy's neck when he was 8 years old.
